That's pretty slick. I would probably finally use those 7 segment LEDs that are collecting dust on my PPDB. I typically just use TV out for simplicity of setup, but this would change that and enable me to use the PPDB by itself (no TV/VGA monitor/serial LCD/etc).

The breadboard is 0.06" higher than the tops of the headers on the board. You'll want to make sure pins are long enough to reach the headers across this gap.

As kuroneko mentioned, the first pin (left most) on the second display header is 0.2" from the last pin (far right) on the first display header. Making the headers spaced so one pin would fit between the two headers.

The last pin (P0) on the header of Propeller pins is about 0.15" from the first pin the first display header. Since these headers are so close together, I'm afaid your board might block part of the P0 header.

What a great idea!
Will the board come assembled?
I know you said it comes with the parts.
I don't see any caps across the power power pins of the ICs, are there any?
This would be a great addition to my PPDB, so far I have never used the displays, due to lack of drivers.

So Im not the only one. I found the old PDB for stamps/SX 7-segs much more useful. They just aren't worth wiring up on the PPDB unless I add jumpers to make them 7-segs. Even then. I'm always going to video or TTL out.

I just created the fonts 0-9 and A-Z
I post it here if someone else wants them
My full spin driver for the 17seg Led driver should be avilable soon.

I think I'm going to switch the two and three pin headers for female headers. I'm thinking with female headers, I can use normal hookup wire to make the necessary connections.

I'm curious if any of you prefer the male headers and why?

For this application the female connectors like the ones used on the development board make more sense for this particuar application. I think I have some and may switch those out. For anyone keeping the male headers you may want to switch those with straight ones that stick up. The original ones that lay down may interfere with projects on the proto area.

Other than that it works great and now I can finally use those nice displays! I think I'm just going to leave it on the board all the time now.
